Runs mix format against staged Elixir files.
Options
:check_only— usemix format --check-formatted. Fails instead of mutating.:args— extra CLI args appended after the task name (and the--check-formattedflag when:check_onlyis set). Default[].
Argument order: mix format [--check-formatted] <user_args...> -- <files...>.
The -- stops mix format parsing a --prefixed filename as an option.
Defaults
stage_fixed: truefiles: ~w(**/*.ex **/*.exs **/*.heex)— matches root and nested paths.
